Amazon.in - Cancelled mu order twice and told me to buy the same product for 3000 rs more

I had ordered a external hard drive on ** January **** on amazon india for ****rs for my friend.
After some time the order got cancelled . When i contacted the customer service they told me that the item was out of stock. so i next day on ** nd
I ordered the same product and emailed amazon customer service stating if any problem with that order too,got a reply from them that the item will be successfully delivered by date and they said they had confirmed with the seller . I trusted them and contacted my friend and said the item will reach in time so he paid me rs ****.
Then the very next day item again cancelled by amazon for no reason. They cheated me , now when i called the customer care they told me to buy the same item for **** rs . So i have to pay **** rs more . So i understood that they cheated me by giving those offers and claiming they will give the product. After that they told me to give ***rs compensation and thats all.Till now i did not get it. I felt shame when my friend asked me if i am also cheating him by telling him that it was available for ****rs.
Now he felt that i cheated him.They have removed both order details from amazon account .
I need the product for the same price or i need compensation for the loosing dignity . Amazon cheated me twice and their customer support told me lie stating that they have everything fine and under control.
